Single inclusive forward hadron production at next-to-leading order
Abstract
We discuss single inclusive hadron production from a high-energy quark scattering off a strong target
color field in the color glass condensate formalism. Recent calculations of this process at the next-toleading-order
accuracy have led to negative cross sections at large transverse momenta. We identify the
origin of this problem as an oversubtraction of the rapidity divergence into the Balitsky-Kovchegov
evolution equation for the target. We propose a new way to implement the kinematical restriction on the
emitted gluons to overcome this difficulty.
